This paper surveys the ontological and aesthetic character of puzzles in worlds with storytelling potential, storiable worlds (potential storyworlds). These puzzles are termed fiction puzzles. The focus is on the fiction puzzles of videogames, which are accommodated to John Dewey's pragmatist framework of aesthetics to be examined as art products capable of producing aesthetic experiences. This leads to an establishing of analytical criteria for estimating the value of fiction puzzles in the pragmatist framework of aesthetics.
